Aromatic Oil Extraction Tank

Chat Online Leave Message

Working Principle

An aromatic oil extraction tank is a refining equipment for recovering aromatic oil substances. Its extraction principle is as follows: the extraction solvent and plant materials containing aromatic oils are added to the tank according to a specified technological ratio. The jacket is used for heating, and once the evaporation temperature is reached, the input of jacket steam is adjusted to maintain the internal temperature for a set period as per the process requirements. The aromatic oils then volatilize, and the vapor is cooled by a cooling system. The cooled material is separated by an oil-water separator.

 

Characterized by simple operation, reliable technology, and high extraction efficiency, aromatic oils are predominantly found in plants, generally distributed in petals, leaves, or tree trunks. Although extraction processes for different plant parts are largely similar, the oil content and extraction yield vary.

Structural Characteristics

The main body of the aromatic oil extraction tank is fabricated from high-quality non-toxic and clean 304 stainless steel. All other parts not in contact with materials adopt [specified materials]. The sections in contact with the liquid medicine are designed without dead corners, and the surface is smoothly treated to prevent material accumulation and facilitate cleaning. The equipment structure is rationally designed to meet process requirements and allows for easy cleaning.

Process Nozzles and Functional Components

The extraction tank is equipped with process nozzles for CIP (Clean-In-Place) ports, drinking water, steam, condensate water, thermometer, pressure gauge, liquid outlet, circulation, liquid inlet, and reflux. It is also fitted with a cleaning ball to enable online cleaning.

Filtration System

  • Bottom Filtration: The tank adopts bottom filtration with a large filtration area.
  • Filter Mesh: The mesh is firm, has sufficient strength to resist damage, is detachable for easy cleaning, and effectively achieves solid-liquid separation.

Auxiliary Equipment

  1. Foam Catcher: Captures material foam efficiently to prevent overflow, with easy-cleaning features.
  2. Condenser: Effectively condenses the liquid medicine into a liquid state, designed for convenient cleaning.
  3. Cooler: Easy to clean, it cools the condensed liquid medicine to below 30°C to optimize oil-water separation.
  4. Oil-Water Separator: Facilitates efficient separation of oil and water from the cooled liquid medicine, equipped with a protective structure to prevent the medicine from flowing into the recovered volatile oil.
  5. Filter: Enables continuous operation, avoids liquid outlet blockage caused by residue accumulation, and is easy to disassemble and clean.

Heating System

The extraction tank is equipped with multi-section jacket and a central heating drum, allowing simultaneous or independent heating. This design ensures the liquid medicine remains in a gentle boiling state, prevents violent boiling, and achieves excellent heating efficiency.

Electrical Protection

The electrical components are sealed to prevent water erosion, ensuring operational safety and reliability.
